Flashed the new firmware, then flashed this new update.
Everything seems to be working fine, except I'm curious if anyone else has this issue:
With sense 6, HTC put the blinkfeed launcher, gallery, TV, etc on the play store. These don't show up under My Apps for me but can be found through searching. I have the option to update blinkfeed, but the update doesn't work. "Package file was not signed correctly. Uninstall the previous copy of the app and try again."
Can anyone else recreate this?
